Our Approach
How we build interview coaching you can actually trust
OfferStory AI is an independent app. It is made by one person who builds it by directing AI tools, not by a team of software engineers. It started from a practical problem: the practice options for behavioral interviews were either expensive or too generic to help with the specific answers you have to give.
The aim is a tool that is affordable, private (audio only, no camera), and grounded in published interview research rather than generic tips.
✓ What we are
- An independent app, made by one person directing AI tools
- Researched, with the sources cited on this page
- Practitioners of the frameworks we teach (we use STAR ourselves)
- Committed to updating our content as new research emerges
✗ What we're not
- Professional career counselors or certified coaches
- Guaranteeing interview results or job offers
- A replacement for professional career guidance
- Claiming expertise we don't have
We believe in honest transparency. You deserve to know exactly who's behind the tool you're using. Read our full disclaimer for more.
Every question, feedback prompt, and coaching insight in OfferStory AI is grounded in established interview science. Here's our methodology:
Research-Backed Frameworks
Our STAR coaching is based on the behavioral interviewing methodology pioneered by industrial-organizational psychologists. Structured interviews have been shown to be significantly more predictive of job performance than unstructured ones (Schmidt & Hunter, 1998).
Curated Question Bank
Our 40+ questions are curated from real interview reports, published hiring guides, and common patterns reported by candidates at top tech companies. We categorize them by role (PM, SWE) and competency area.
AI Grounded in Structure
Our AI feedback isn't generic encouragement. It analyzes your answer against the STAR framework, quotes your exact words, and provides specific suggestions — the same approach a structured mock interview would use.
Continuous Updates
We regularly review new research on interview effectiveness, anxiety reduction techniques, and AI coaching best practices. When the evidence evolves, our product evolves with it.
We draw on research from these areas and organizations. For specific citations, see the sources section on our blog posts.
